' COMBINED CREMATORY AND LA TRINE.

Patented Sept. 26, 1905.

Application filed May 1904. Serial No. 206,435.

To all whom it may concern:

Be it known that I, FRED P. SMITH, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new, and useful Improvement in a OombinedOrematory and Latrine, of which the following is a full description.

The object of my invention is to produce a combined crematoryand latrine capable of being taken apart and removed from place to place, which is at all times kept cool and free from smell or bad odors, and which may be erected and used at any convenient point without nuisance to the surroundings.

The accompanying drawings illustrate the invention, of which Figure 1 is a plan View of the interior of the crematory and latrine; Fig. 2, a vertical sectional view of the same on line 2 2, Fig. 1; Fig. 3, a section on line 3 3, Fig. 2; Fig. 4, a section taken on line 4 4, Fig. 2; Fig. 5, a vertical section on line 5 5, Fig. 3; Fig. 6, a front elevation of the device.

Located within a furnace are shown in the drawings a series of hollow rotatable gratebars forminga grate 1, which are so placed asto receive garbage or-other refuse material through the dump-holes 2. Below this grate is seated another one, 3, composed, like the one above, of hollow rotatable bars. The

space between the grates is open, and from this space there is an outlet to a chimney 5, furnished with an adjustable damper 4. The material burned or ignited upon the upper grate 1 is when in proper condition dropped upon the lower grate 3, and when sufficiently consumed is dropped into the ash-pit 6. When fires are ignited upon both grates and the damper 4 is open, there is a downdraft through the upper grate and an updraft through the lower grate. hollow metallic frame orv shell 7, and in the space between the walls of this frame the 'air from without circulates freely, entering therein through the openings 8. The hollow gratebars are also journaled in the inner walls of this shell, and the air passing through the bars is warmed in its passage and, together with the air entering from without, enters the space between the walls of the outer shell and escapes into the crematory through the perforations 9 in the inner wall of the frame.

Projecting from the furnace is a latrine 10, which extends to a distance suitable to be furthe fire on grate 3.

Surrounding these grates is a nished with the closets 11. Below these closets is a separating-plate 12, which divides the latrine into an upper and a lower chamber 13 and 14. The solid matter from the closets falling upon the plate 12 remains there until desiccated or swept off, and the liquid passes through the apertures 15 and falls upon the floor of the lower chamber 14. This lower chamber is also divided in two by theupright partition-wall 16', Fig. 4, which extends nearly to the end of the latrine, leaving a space 17 at its rear end. Between the latrine and the furnace is interposed a chamber 18. It is provided with dump-holes l9, and within this chamber at a level below the floor 12 of the latrine is located a pan 20. Upon this pan may be dumped garbage or other refuse material, and the solid desiccated matter from the floor 12 may be swept upon it. Below the pan and at the bottom of chamber 18 is another pan 21, which may be called an evaporating-pan. Its office is to receive the liquid matter dripping from the pan 20 and also from the floor of chamber 14 and evaporate it. This lower space between the floors is provided with doors 22. The partition-wall 16 divides the lower chamber 14 in two, and in one of the chambers thus formed the adjustable damper 23 is placed, and when this damper is closed and the damper 4 is open the draft to thechimney is direct from the furnace through damper 4 and draws off the foul odors from the latrine, which pass over the floor 12, through chamber 18, and over When the damper 23 is open and 4 is closed, the heat and products of combustion pass from the grates through chamber 18, above floor 12, through opening 17, into chamber 14, over pan 21, into ash-pit 6,'and thence through lower passage to the chimney.

On the front elevation of the device, Fig. 6, are shown the usual furnace-doors 24 25 26, which may be opened or .closed, as required. Air admitted through the upper and lower of these doors will maintain the updraft through the grate 3 and the downdraft through grate 1 when the damper 4 is open.

The whole device is constructed in sections and jointed, so as to be taken apart, removed, and reassembled. These joints are shown in the drawings-in Fig. 2 at A B O D E, in

the chamber between the furnace and the latrine at H and I, and in the latrine at K, L, M,

and N. The front of the apparatus is also shown in detachable sections and plates at 0 P Q R S T, and the sections are so made as to lit over the ends of the grate-bars and form a bearing in which they can be rotated when required, leaving them so exposed that the outer air may pass through them and enter the hollow space between the walls of the frame.

The entire device is capable of consuming garbage or other refuse matter while carefully providing for and evaporating the drainage, and combined with a latrine whose parts cooperate with the erematory which takes oif and consumes all odors, consumes the solids, and evaporates the liquid therein, and the whole apparatus is constructed to be taken apart in sections moved from place to place as required, and reassembled when thus removed.

l/Vhat I claim, and desire to secure by Letters Patent, is

1. In a combined crematory and latrine, a furnace, and a latrine having a separatingchamber located between them and communicating with both, the latrine provided with a floor for the solid and liquid matter and openings in the floor to allow the liquid matter to escape in combination with :uljustable dampers and means for opening and closing them to draw the odors and vapors over or under the floor oi the latrine as desired.

2. In a combined crematory and latrine, a furnace composed ol two or more grates com posed of hollow rotatable bars and means for producing an upward or downward draft to a chimney, in combination with a latrine having an upper and lower compartments, dampers and means for adjusting the same to draw ofl the air from the upper compartment and induce a circulation of heat through the lower compartment in its passage to the chimney, and constructed in removable sections, to permit the device to be taken apart, removed and its parts reassembled after removal.

1n testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
